Interview Question

What are some limitations of Selenium?

Selenium cannot test desktop apps or web services and depends on external libraries for advanced functionality

Answer

  1. ✓Cannot test desktop applications
  2. ✓Cannot test web services or APIs
  3. ✓Programming language knowledge is required for writing robust scripts
  4. ✓Depends on external libraries for:
    • ✓Logging → Log4j
    • ✓Test Framework → TestNG, JUnit
    • ✓Reading Excel files → Apache POI

Real-World Example

A QA engineer cannot use Selenium to test a Windows desktop app or a REST API — they need tools like WinAppDriver or REST Assured for those.

Code Example

Java
// Selenium cannot do this — use REST Assured for APIs
// Selenium cannot do this — use Appium for desktop

// Selenium can only do this:
WebDriver driver = new ChromeDriver();
driver.get("https://automateqa.online");
driver.quit();

Best Practices

  • ✓Use REST Assured for API testing
  • ✓Use Appium for mobile/desktop testing
  • ✓Always combine Selenium with TestNG and Log4j for a complete framework

Common Mistakes

  • ✓Trying to use Selenium for API or desktop testing
  • ✓Not knowing that Selenium alone is not a complete framework
